If you receive a traceback error message during installation, you can usually save it to a diskette.

If you do not have a diskette drive available in your system, you can scp the error message to a remote system.

When the traceback dialog appears, the traceback error message is automatically written to a file named /tmp/anacdump.txt. Once the dialog appears, switch over to a new tty (virtual console) by pressing the keys Ctrl+Alt+F2 and scp the message written to /tmp/anacdump.txt to a known working remote system.

This error occurs in some systems where links to /tmp/ are symbolic to other locations or have been changed since creation. These symbolic or changed links are invalid during the installation process, so the installation program cannot write information and fails.

If you experience such an error, first try to download any available errata for anaconda. Errata can be found at:
